What is the applications of angular momentum?
Angular momentum is used in various applications in physics and engineering, such as in analyzing the motion of objects in rotation (like spinning tops or satellites), understanding the behavior of gyroscopes, and explaining phenomena like the conservation of angular momentum in celestial bodies. It is also crucial in quantum mechanics for describing the rotational properties of particles.
What angular acceleration is necessary to increase the angular speed of a fan blade from 8.5 rads per second to 15.4 rads per second in 5.2 seconds?
Wf - Wi = a*t, where Wi and Wf are the initial and final angular velocities, respectively, a is the angular acceleration, and t is time. So, a*t = 15.4 rad/s - 8.5 rad/s = 6.9 rad/s, thus a = 6.9 rad/s / 5.2 s = 1.3 rad/s2.
What puts out more air- a two blade fan or a four blade fan?
A four-blade fan typically moves more air than a two-blade fan because it has more surface area to push the air. This allows the four-blade fan to generate more airflow with each rotation compared to a two-blade fan.
If 3 ounce weight is on a 15 inch fan rotating at 900 rpm so What is the force on the fan blade in pounds?
To calculate the force on the fan blade, we first convert the weight from ounces to pounds (3 ounces = 0.1875 pounds). Then, we use the formula: force (in pounds) = weight (in pounds) x radius (in feet) x angular velocity squared (in rad/s). Given the radius of 15 inches (convert to feet by dividing by 12), and an angular velocity of 900 rpm (convert to rad/s by multiplying by 2π/60), we can calculate the force on the fan blade.
The blades of a fan keep on moving for sometime even after the fan is switched off?
This phenomenon is due to inertia, where the blades of the fan will continue to spin briefly after the fan is turned off until the force causing them to move is dissipated. The air resistance and momentum of the spinning blades contribute to this delayed stopping effect.

Explai your ovservation into what happened to the blade of the electric fan when it turn off?
The blade will go off if the electric fan is turned off.
What is the angle in 6 blade fan?
six blades of a fan divide 360 degrees into six segments. each angular segment therefore is of 60 degrees each. So angle between blades of a 6 blade fan is 60 degrees.
A rotating fan blade has kinetic energy when rotating with constant angular velocity when the angular velocity is reduced to one third what will happen to the kinetic energy?
The kinetic energy of the fan blade will decrease to one ninth of its original value because kinetic energy is proportional to the square of the angular velocity. So, if the angular velocity is reduced to one third, the kinetic energy will decrease to (1/3)^2 = 1/9 of its original value.
What angular acceleration is necessary to increase the angular speed of a fan blade from 8.5 rads per second to 15.4 rads per second in 5.2 seconds?
Wf - Wi = a*t, where Wi and Wf are the initial and final angular velocities, respectively, a is the angular acceleration, and t is time. So, a*t = 15.4 rad/s - 8.5 rad/s = 6.9 rad/s, thus a = 6.9 rad/s / 5.2 s = 1.3 rad/s2.
Will a hair dryer suck instead of blow if the fan blade is turned around?
A: That will be true ONLY if the blades have a pitch to it
What could be causing the noise coming from the bathroom fan when it is turned off?
The noise coming from the bathroom fan when it is turned off could be caused by a loose or damaged fan blade, motor, or mounting bracket. It is recommended to have a professional inspect and repair the fan to prevent further damage.

How can wind be turned into energy?
By causing it to rotate a fan or blade of some sort that is conected to a generator which in turn gives out an electric curent.
What could cause a central air conditioner fan to not turn on?
many times it'd the run capacitor (that cylinder) where the wires from the fan run. if the fan is turned on and you hear a hum, tap the blade. if the fan turns, then that's the problem.
What type of fan blade do you need for a serpentine belt on zz4 motor?
a reverse fan blade and fan clutch
